Aims and objectives
Atrial fibrillation (AF) is the most common type of heart arrhythmia,
which increases the risks of death,
stroke and other thromboembolic complications.
[1] Stasis in the left atrium (LA) flow is regarded as one of the main factors of thrombus formation in AF patient.
(2) However,
the knowledge of hemodynamic changes in AF remains rather limited.
4D flow MRI is a novel,
currently available non-contrast technique of multidirectional blood flow assessment.
3D cine velocity encoding acquisition provides data of complete time-resolved 3-directional velocity field to complex flow analysis.
4D flow MRI has different tools for quantitative flow evaluation in any direction and visualization of flow patterns in a 3D-volume.
In recent years,
a number of studies have analyzed the normal and altered LA hemodynamics by using flow-sensitive 4D MRI sequences [3-6].
The purpose of this study was to reveal altered PVs and LA flow in patients with atrial fibrillation by 4D Flow MRI.
